Abstract
Fracture of integrated metal microelectrodes likely happens during the thermal bonding process of PMMA [poly (methylmethacrylate)] microfluidic chips. In this paper, the fracture behaviors are studied. The fracture is mainly caused by the plastic deformation of the electrode plate (the PMMA plate with microelectrodes) and the thermal stress of microelectrodes, which is due to the high bonding temperature. To decrease the bonding temperature, a plasma assisted thermal bonding method is evaluated and first used to eliminate the fracture of microelectrodes. in this process. the surface of the cover plate (the PMMA plate with microchannels) is modified using oxygen plasma before the electrode plate is thermally bonded to the cover plate. The parameters of the oxygen plasma treatment are optimized, and the contact angle is decreased from 71.7 degrees to 43.6 degrees. The thermal bonding temperature is optimized, which decreases the temperature from 100 degrees C to 85 degrees C. Testing of bonding strength shows an average failure pressure of 1.75 MPa, which is comparable to the bonding strength of 1.46 MPa for chips bonded at 100 degrees C without plasma modification. In order to demonstrate this bonding method, a PMMA microfluidic chip with integrated copper interdigitated microelectrode arrays for AC electroosmotic pump is fabricated. (C) 2009 Elsevier B.V.

3.毕业论文的外文文献及翻译怎么弄
参考文献是在学术研究过程中，对某一著作或论文的整体的参考或借鉴.征引过的文献在注释中已注明，不再出现于文后参考文献中. 外文参考文献就是指论文是引用的文献原文是国外的，并非中国的。
原文就是指原作品，原件。即作者所写作品所用的语言。
如莎士比亚的《罗密欧与朱丽叶》原文是英语。 译文就是翻译过来的文字，如在中国也可以找到莎士比亚《罗密欧与朱丽叶》的中文版本。
这个中文版本就称为译文 回答者： xffjy - 见习魔法师 三级 10-22 11:52。

1、Synthesis and characterization of a novel high-oil-absorbing resin 作者：Xiao-Ming Zhou;Cheng-Zhi Chuai 刊名：Journal of Applied Polymer Science 出版日期：2010 期号：No.6 卷号：Vol.115 摘要：A high-oil-absorbing resin, which was a low crosslinking resin, was synthesized by conventional suspension copolymerization in this study. The effects of the monomer ratio, crosslinker, initiator, ratio of water to oil, and defined optimum reaction conditions were studied. The highest oil absorptivity of the resin was about 11.5 g/g in diesel and the oil-absorption saturation time was 3 days when。
